此病从肺气闭塞所致，因为肺主一身之气并运行水道，肺气闭塞则水液不能下行而泛滥于皮肤，症状与风水相似，只是不恶风作为区别。

Water qi moves upward due to agitation by wind pathogen. The pulse is floating and surging, with symptoms of bone and joint pain, aversion to wind, and edema of the face, eyes, and four limbs. Treatment should primarily focus on dispelling wind; once the wind is eliminated, the water will naturally descend.
Mahuang Fuzi Tang (Ephedra and Aconite Decoction)
Ephedrae Herba (Mahuang, 麻黄) (3 liang), Glycyrrhizae Radix et Rhizoma (Gancao, 甘草) (1 liang), Aconiti Lateralis Radix Praeparata (Fuzi, 附子) (1 piece).
Add seven sheng of water, first decoct Mahuang and remove the foam on the surface, then add the remaining herbs and decoct until two and a half sheng remain. Take warm, eight fen per dose, three times daily. (This formula is used for Fengshui syndrome complicated by cold.)
Yueshi Tang (Jade Pillow Decoction)
Ephedrae Herba (Mahuang, 麻黄) (6 liang), Gypsum Fibrosum (Shigao, 石膏) (0.5 jin), Zingiberis Rhizoma Recens (Shengjiang, 生姜) (3 liang), Jujubae Fructus (Dazao, 大枣) (15 pieces), Glycyrrhizae Radix et Rhizoma (Gancao, 甘草) (2 liang).
Add six sheng of water, first decoct Mahuang and remove the foam on the surface, then add the remaining herbs and decoct until three sheng remain. Divide into three warm doses. (This formula is used for Fengshui syndrome complicated by heat.)
Xiangru Wan (Perilla Leaf Pills, from *Waitai Mi Yao*)
Dry Elsholtziae Herba (Xiangru, 香薷) (50 jin).
Finely chop, place in a pot, cover with water several inches above the herb, decoct until the aroma is exhausted, filter the dregs and clarify the liquid, then slowly reduce over low heat until it can be formed into pills. Make pills the size of wu zi (Cocculus trilobus seeds). Take 50 pills per dose, three times daily. The dosage may be slightly increased, stopping when urination becomes smooth. No dietary restrictions.
Rushu Wan (Elsholtia and Atractylodes Pills)
Dry Elsholtziae Herba (Xiangru, 香薷) (1 jin), Atractylodis Macrocephalae Rhizoma (Baizhu, 白术) (7 liang).
First grind Baizhu into powder, then decoct Xiangru in concentrated juice and mix with the powder to form pills the size of wu zi. Take 10 pills with warm water, four to five times during day and night. This effectively promotes urination.

The above three formulas all employ bitter, acrid, and bland methods to promote diuresis. Li Dongyuan stated: For Fengshui syndrome, one should use acrid flavors to disperse it, bitter flavors to purge it, and bland flavors to leach out dampness, thereby dispersing dampness from both upper and lower jiao.
This condition arises from lung qi obstruction. Since the Lung governs all qi and regulates water passages, lung obstruction prevents water from descending, causing it to overflow into the skin. The presentation resembles Fengshui, but differs by the absence of aversion to wind.

Sargassum (Haizao, 海藻), Euphorbiae Pekinensis Radix (Daji, 大戟), Rheii Radix et Rhizoma (Dahuang, 大黄), Swieteniae Semen (Xuisui Zi, 续随子) (dehusked, each 1 liang).
